What Is Secondary Memory Of Computer? Secondary memory is also termed as external memory and refers to the various storage media on which a computer can store data and programs. The Secondary storage media can be fixed or removable. Fixed Storage media is an internal storage medium like hard disk that is fixed inside the computer.
What is secondary memory? Secondary memory is where programs and data are kept on a long-term basis. Common secondary storage devices are the hard disk and floppy disks. The hard disk has enormous storage capacity compared to main memory. The hard disk is usually contained in the systems unit of a computer.
What is secondary memory answer? Answer: Secondary Memory. Secondary memory refers to storage devices, such as hard drives and solid state drives. It may also refer to removable storage media, such as USB flash drives, CDs, and DVDs. Unlike primary memory, secondary memory is not accessed directly by the CPU.
What is secondary memory in computer and its types? Secondary memory is called also Backup or Auxiliary memory. Primary memory has two categories like as RAM and ROM. Secondary memory has four categories like as Magnetic Storage, Optical Storage, Flash storage, and Online Cloud System. Primary memory is more costly to secondary memory.

What is the purpose of secondary memory?
Secondary memory is used for storage purposes.
Files and data which are currently not in use by the processor of a computer is stored in the secondary memory. These are stored as temporary files and are not permanent. This helps the computer to access files faster when accessed by a user.
What is primary and secondary memory with example?
Primary memory is also known as Main memory or Internal memory. Secondary memory is also known as External memory or Auxiliary memory. 7. Examples: RAM, ROM, Cache memory, PROM, EPROM, Registers etc. Examples: Hard Disk, Floppy Disk, Magnetic Tapes etc.
What is secondary memory give three examples?
Secondary memory devices include magnetic disks like hard drives and floppy disks ; optical disks such as CDs and CDROMs ; and magnetic tapes, which were the first forms of secondary memory.
What is difference between primary and secondary storage?
Primary storage refers to the main storage of the computer or main memory which is the random access memory or RAM. Secondary storage, on the other hand, refers to the external storage devices used to store data on a long-term basis.
What 2 is secondary memory explain with examples?
Secondary memory refers to storage devices, such as hard drives and solid state drives. It may also refer to removable storage media, such as USB flash drives, CDs, and DVDs. For example, a computer may have a one terabyte hard drive, but only 16 gigabytes of RAM.
What are the two types of secondary memory?
Depending on whether secondary memory device is part of CPU or not, there are two types of secondary memory – fixed and removable.
What is secondary data example?
Secondary data refers to data that is collected by someone other than the primary user. Common sources of secondary data for social science include censuses, information collected by government departments, organizational records and data that was originally collected for other research purposes.
How many types of secondary memory are there in computer?
There are three main types of secondary storage in a computer system: solid state storage devices, such as USB memory sticks. optical storage devices, such as CD, DVD and Blu-ray discs. magnetic storage devices, such as hard disk drives.
Which is the following is a secondary memory device?
An optical disk is also known as a CD-ROM or compact disk and it is a secondary memory device.
What are primary and secondary memory in computer?
Primary memory is the main memory of the computer which can be directly accessed by the central processing unit, whereas secondary memory refers to the external storage device which can be used to store data or information permanently.
Is ROM a secondary memory?
Computer memory is of two basic type – Primary memory(RAM and ROM) and Secondary memory(hard drive,CD,etc.). Random Access Memory (RAM) is primary-volatile memory and Read Only Memory (ROM) is primary-non-volatile memory.
What is a secondary device meant to do?
Secondary storage devices primarily refer to storage devices that serve as an addition to the computer’s primary storage, RAM and cache memory. Since they always consist of non-volatile memory, they allow the user to permanently store data on them.
What is the difference between primary and secondary name of a file?
primary name of a file is the actual name of a file while secondary name of file is the extension of that file.
What are primary and secondary devices?
Therefore, there are different levels of data storage, which may may be referred to as primary and secondary storage. A computer’s internal hard drive is often considered a primary storage device, while external hard drives and other external media are considered secondary storage devices.
Why are primary and secondary memory needed in a computer system?
For instance, when you save your work in Word, the file data moves from primary storage to a secondary storage device for long-term retention. Likewise, a primary storage device retrieves data from a secondary source to speed up access.
What is not an example of secondary memory?
The correct answer is R.A.M. R.A.M is not an example of a secondary storage device.
What is an example of secondary research?
Common examples of secondary research include textbooks, encyclopedias, news articles, review articles, and meta analyses. When conducting secondary research, authors may draw data from published academic papers, government documents, statistical databases, and historical records.
What is called secondary data?
Secondary data is the data that has already been collected through primary sources and made readily available for researchers to use for their own research. The data may also have been collected for general use with no specific research purpose like in the case of the national census.
Why do computers need secondary storage?
Secondary storage is needed to keep programs and data indefinitely. Secondary storage is non-volatile , long-term storage. It is used to keep programs and data indefinitely. Without secondary storage all programs and data would be lost the moment the computer is switched off.
Is Microprocessor a secondary storage device?
Because the RAM is connected directly to the CPU via the memory bus, the CPU can access data stored in RAM very quickly. While the computer’s primary internal hard drive is the most common secondary storage device, other devices may be considered secondary storage devices as well.
What are the two types of memory?
Internal memory, also called “main or primary memory” refers to memory that stores small amounts of data that can be accessed quickly while the computer is running. External memory, also called “secondary memory” refers to a storage device that can retain or store data persistently.
